“…The genetic data reported here adds to the number of studies indicating that Patagonian Hoki around southern South America do not belong to a single panmictic unit (D'Amato, 2006, Machado-Schiaffino andGarcia-Vazquez, 2011). However, combining genetic data with associated information on individual fish natal area and adult movements derived from otolith trace element analyses (Schuchert et al, 2010) provides new insights into the biological significance of, and underlying mechanisms driving, this population structure.…”

“…The high level of haplotypic diversity and low π value in E. tetradactylum populations in Bay of Bengal and Australian populations suggest that this fish could have experienced a population expansion after a period of low effective population size (Grant and Bowen, 1998). This type of genetic structure has been observed in threadfin fish, E. rhadinum (Sun et al, 2013), long-tailed hake, Macruronus magellanicus (Machado-Schiaffino and Garcia-Vazquez, 2011) and fat greenling, Hexagrammos otakii (Habib et al, 2011 population expansion in most of the E. tetradactylum populations. Moreover, the haplotype network also confirmed recent population expansion following a population bottleneck in most of the studied populations.…”

Eleutheronema tetradactylum is an important commercial fish species exposed to intense exploitation both in Southeast Asian countries and Northern parts of Australia. Research on the population structure of E. tetradactylum in these coastal waters is substantial in order to ensure sustainable use and appropriate resource management. In this study, genetic variation, diversity and population structure of E. tetradactylum among four FAO fishing areas, along South Asian countries, were evaluated using cytochrome c oxidase subunit I (COI) gene. Totally 30 sequences of COI gene were collected from four FAO fishing areas. Among these 30 individuals, 18 distinct haplotypes were defined. High levels of haplotype diversity (hd = 0.952 ± 0.096) and nucleotide diversity (π = 0.01536 ± 0.00312) were observed in the population within the Bay of Bengal. No haplotype and nucleotide diversity were observed in South China Sea population. Hierarchical analysis of molecular variance (AMOVA) indicated that whereas 0.81% of the genetic variation occurred within the populations, 7.09% occurred among populations. Significant genealogical branches were recognized in North Australian populations (one clade), South China Sea populations (one clade), Arabian Sea and Bay of Bengal populations (one clade on the neighbor-joining tree). These results suggested that E. tetradactylum populations in FAO fishing areas 51, 57 and 61 have developed different genetic structures. Tests of neutral evolution and mismatch distribution suggest that a population growth of E. tetradactylum may take place in these fishing areas.
